Newcastle United have completed the signing of Toulouse midfielder Moussa Sissoko, making him the club's fourth new signing of the window.

Moussa Sissoko has signed until 2018

Sissoko, 23, has put pen-to-paper on a six-and-a-half year deal at St. James' Park and will wear the No. 7 shirt. He played nearly 200 times for Toulouse but had been frozen out of the first team picture after threatening to sign a pre-contract agreement with the Magpies.

Nancy defender Massadio Haidara will be joining Newcastle after a deal was agreed, the French Ligue 1 club have announced on their website.

The deal for Haidara is on the verge of being completed

Haidara, 20, will travel to Newcastle for a medical, with the switch likely to be finalised on Tuesday. The Magpies tabled an offer four days ago, but it had been thought he was hoping for a switch to Serie A.
